Unfortunately, once the F plasmid has been transferred, the recipient becomes "male" as well. This is a bit of a bummer, because bacteria carrying the F plasmid are more susceptible to bacteriophage attack. There's also no homosexuality here - the F plasmid encodes coat proteins that prevent the F pilus from attaching to the carier.

In other words, it's less roughly the microbial equivalent of a penis, except that everyone you have sex with turns into a man afterwards and you're not able to be gay and if you have one you give off a scent that causes dogs to come and attack you.
